With this demo, you can supply an Input string and see the combinations that are confusable with it,
using data collected by the Unicode consortium. You can also try different restrictions, using characters valid in
different approaches to international domain names. For more info, see Data below.

Restriction

Total raw values: 0

Confusable Results

Confusable characters are those that may be confused with others (in some common UI fonts),
such as the Latin letter "o" and the Greek letter omicron "ο". Fonts make a difference: for example,
the Hebrew character "ס" looks confusingly similar to "o" in some fonts (such as Arial Hebrew), but not in others.
See also unaccented Latin Characters..

The data for confusables and restrictions is from UTS39. You can suggest
additions or changes to the Unicode data for future versions of that standard.

The "UTS46+UTS39" test checks mixed scripts according to the levels in
Unicode Security Considerations (proposed update),
such as "aα", "a٠b", or "Ꭰa1".
It also checks for Hans vs Hant (万丟); for different number systems(1٦, ٦۶); and for duplicate non-spacing marks (ä̈).

The restrictions are purely on a character level. For a more detailed view, see idna.

Caveats

The Unicode data is designed for testing, not enumerating, so not all combinations are generated in this demo;
In particular, where a character is confusable with a sequence, not all combinations are generated.
